I have a problem that I cannot wrap my head around.
I'm using Apache and PHP
I need to get:
http://localhost.com/cat_ap.php?nid=5964
from
http://localhost.com/cat_ap~nid~5964.htm
How do I go about changing that around? I have done more simple mod rewrites but this is slightly more complicated. Can anyone give me a leg up or point me in the right direction
RewriteRule ^/cat_ap~nid~(.*)\.htm$ /cat_ap?nid=$1 [R]
The [R] at the end is optional. If you omit it, Apache won't redirect your users (it will still serve the correct page).
If the nid part is also a variable, you can try this:
RewriteRule ^/cat_ap~([^~]+)~(.*)\.htm$ /cat_ap?$1=$2 [R]
EDIT: As Ben Blank said in his comment, you might want to restrict the set of valid URLs. For example, you might want to make sure a nid exists, and that it's numerical:
RewriteRule ^/cat_ap~nid~([0-9]+)\.htm$ /cat_ap?nid=$1
or if the nid part is a variable, that it only consists of alphabetical characters:
RewriteRule ^/cat_ap~([A-Za-z]+)~([0-9]+)\.htm$ /cat_ap?$1=$2
Assuming the variable parts here are the "nid" and the 5964, you can do:
RewriteRule ^/cat_ap~(.+)~(.+).htm$ ^/cat_ap?$1=$2
The first "(.+)" matches "nid" and the second matches "5964".
If you want everything arbitrary:
RewriteRule ^/(\w+)~(\w+)~(\w+)\.htm$ $1?$2=$3 [L]
Where \w is equal to [A-Za-z0-9_]. And if you want to use this rule in a .htaccess file, remove the leading / from the pattern.

I have a website with joomla and I need to redirect (301) some links
They are in this form (index.php?Itemid= identify them - all links that doesn't have this part shouldn't be redirected)
/index.php?Itemid=544&catid=331:savona&id=82356:smembramento-dei-cantieri-baglietto-di-varazze-lopposizione-delle-maestranze&option=com_content&view=article
This should work
RewriteRule ^index.php?Itemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301]
But the first ? (question mark) seems to cause problems.
In fact, if we suppose that the links are without the question mark
/index.phpItemid=544&catid=331:savona&id=82356:smembramento-dei-cantieri-baglietto-di-varazze-lopposizione-delle-maestranze&option=com_content&view=article
I would use
RewriteRule ^index.phpItemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301]
and everything is perfect. But unfortunately real links has that question mark, and I have to find a solution.
What I have to do with that question mark?
Is the ? character escaped? try to add the NE (noescape) flag like this:
RewriteRule ^index.php?Itemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301,NE]
The part behind the question mark is the query string. You can use RewriteCondto determine if it is not empty, and based on that make the decision to redirect.
Note: Query String
The Pattern will not be matched against the query string. Instead, you must use a RewriteCond with the %{QUERY_STRING} variable. You can, however, create URLs in the substitution string, containing a query string part. Simply use a question mark inside the substitution string, to indicate that the following text should be re-injected into the query string. When you want to erase an existing query string, end the substitution string with just a question mark. To combine a new query string with an old one, use the [QSA] flag.
Source: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html
This should help you:
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} Itemid
RewriteRule ^index.php(.*)$ http://www.ligurianotizie.it/archive/index.php$1 [L,R=301]
Every link containing "Itemid" will be redirected, the others not.
I have this code in a .htaccess file..
RewriteEngine On
Options +FollowSymlinks
RewriteBase /
RewriteRule ^(.+)-headquarters-([0-9]+)\.html company.php?lid=$2
Now my question is, what happens if the matching result from the first parentheses contains a hyphen? There is a very good chance a lot of them will. Is this where the ungreedy modifiers come in!?
I don't think in this case you need to make it ungreedy. e.g. test-headquarters-headquarters-42.html will match perfectly fine (with test-headquarters being $1).
But for completeness I will suggest a few options
You can make it ungreedy by adding a ? after it. So your rule would become (although, it this case, there would not be any case where it would result in different behaviour):
RewriteRule ^(.+)?-headquarters-([0-9]+)\.html company.php?lid=$2
You could also choose match anything except a hyphen by using
RewriteRule ^([^-]+)-headquarters-([0-9]+)\.html company.php?lid=$2
I have been using this rule:
RewriteRule ^([^\.]+)/?$ index.php?page=$1 [L]
Which will turn
example.com/page/hello
...into
example.com/index.php?page/hello
However, if I have a file extension on the end of that, say,
example.com/page/hello/doc.html
...it doesn't work. How can I make that URL become:
example.com/index.php?page/hello/doc.html
...and
example.com/page/
...become:
example.com/index.php?page/
Thank you very much if you are able to help with this. I've tried fiddling with the regular expression, but I just can't make it work.
Thanks.
This section of your regex will match one or more characters that are anything except a full stop:
[^\.]+
If you want to match one or more of any character, then just write:
.+
instead
I have this .htaccess RewriteRules, that doesn't work.
RewriteRule ^(.+)\/(.+)\/$ /index.php?pg=$1&act=$2
What this code should do, is transofrm /somthing/other/ into /index.php?pg=somthing&act=other.
Making some test, I discovered that also the pg var is not passed.
I have another line like this, RewriteRule ^(.+)\/$ /index.php?pg=$1 an it work! So, I don't know why the first one didn't work!!
If you don't need to use any other characters than a-z and 0-9 I recommend you to use this:
RewriteRule ^([a-z0-9-]+)/([a-z0-9-]+)$ /index.php?pg=$1&act=$2
It should work.
I know there are other questions that are similar to this.. but I'm really struggling with mod_rewrite syntax so I could use some help.
Basically, what I am trying to do is have the following redirect occur:
domain.com/1/ redirect to domain.com/?id=$1 (also should work for www.domain.com)
What I have so far (that isn't working):
RewriteEngine On
ReRewriteRule ^/([0-9])$ /?id=$1
A few issues.
First is terminology: if you want when a user types domain.com/1/ that the request is served by index.php?id=1, then you are rewriting /1/ to index.php?id=1, not the other way around as you said.
Second, simple typo: RewriteRule, not ReRewriteRule.
Second, [0-9] is the right way to match a number, but it'll only match a single digit. If you want to handle /13 then you should match one or more instances [0-9] by writing [0-9]+.
Third, the target of your rule should be the file you want to serve. / is not a file or an absolute URL, write out the index.php if that's what you mean.
Third, you say you want to handle /1/, but your rule says that the matched request must end in a number, not a slash. If you want to accept the slash whether it's there or not, put that in the rule.
RewriteRule ^/?([0-9]+)/?$ index.php?id=$1 [L]
Does that work?
You've three issues:
RewriteRule is misspelt as point out by Michael, you need to worry about the trailing slash, and you need to stop processing rules when you've found the match:
RewriteRule ^/(\d+)/?$ /?id=$1 [L]
You have misspelled RewriteRule. Otherwise, I think your syntax looks correct.
RewriteEngine On
ReRewriteRule ^/([A-Za-z0-9]+)$ /?id=$1
--^^^---------
Actually, you should probably remove the /:
RewriteEngine On
RewriteRule ^([A-Za-z0-9$_.+!*'(),-]+)$ /?id=$1
------^^^---------
EDIT Added the +. Look at all the answers here. You need a composite of them., including the + and the [L] in addition to what I have here.
EDIT2 Also edited to include alpha characters in the id.
EDIT3 Added special characters to regex. These should be valid in a URL, but it's unusual to find them there.
